Suppose q is the midpoint of pr. use the information to find the missing value. pr = 9x-31 and qr=43; find x

Suppose Q is the midpoint of PR and PR = 9x-31 and QR=43, then the value of x will be 13

The midpoint of a line is the point that bisects or divides the line into two equal parts.

Hence suppose Q is the midpoint of PR, then:

PQ + QR = PR .... 1

and PQ = QR ...... 2

Substitute equation 2 into 1:

QR + QR = PR

2QR = PR

Given that:

PR = 9x-31 and QR=43, then;

2(43) = 9x - 31

86 = 9x - 31

Swap

9x - 31 = 86

Add 31 to both sides

9x - 31 + 31 = 86 + 31

9x = 117

Divide both sides by 9

Hence the value of x is 13

x = 13

Step-by-step explanation:

If Q is the midpoint of PR...then

PR = 2QR...since QR is half the length of PR

;9x - 31 = 86

;9x = 86 + 31

;9x = 117

Hence x = 117/9 = 13

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
